FIELD OF THE INVENTION

The invention relates to automated food processing. More particularly,the invention relates to automated food dispensing, frying and packaginginto individual portion-sized containers such as at a quick-service typerestaurant.

BACKGROUND OF THE INVENTION

In restaurants, especially quick service (fast food) restaurants, fast,consistent, efficient and safe food preparation is essential for asuccessful operation. The quality of the prepared food depends in largepart on the consistency of food preparation. The food must be cookedunder correct conditions for the proper time.

Consistency in food preparation can vary as a result of many factors.For example, people engaged in food preparation often must performmultiple tasks at frequencies that vary with time because of constantlyvarying customer demand throughout the day. For example, lunchtime anddinnertime may be extremely busy while other periods may be relativelyslow. The product mix can vary from hour to hour and day to day. As aresult, the consistency and quality of food may vary. Difficulties inproper scheduling of food production during peak and non-peak periodscan cause customer delays and/or stale, wasted or unusable food.

Food preparation can be labor intensive, and thus, the labor cost can bea large portion of the total cost of the prepared food. An additionalproblem is that in sparsely populated and other areas where quickservice restaurants are located, such as along interstate highways, forexample, recruiting sufficient numbers of suitable employees isdifficult.

Quick service restaurants must be able to effectively meet a variablecustomer demand that is time dependent and not subject to preciseprediction. As a result, stores relying totally on human operators willat times be overstaffed and at other times be under-staffed. Also,problems and potential problems can exist in restaurants where peopledirectly prepare food. Health and safety concerns can also be presentwhere food is prepared directly by people. By reducing or minimizinghuman contact with food and food cooking equipment, health and safetyconcerns can also be reduced or minimized. For example, in the frying offoods, some type of hot fluid, such as cooking oil or shortening must beutilized. The cooking temperatures required can present a concern forhealth and safety.

Although quick service restaurants have existed for many years and nownumber in the tens of thousands, such establishments utilize manuallabor to prepare and process food. While there have been variousimprovements in commercial equipment used for cooking food in quickservice restaurants, such restaurants are believed to be substantiallyall manually operated and relatively labor intensive.

Accordingly, a need exists for an automated, commercially suitable fooddispensing, cooking and packaging device, system and method for friedfoods that can be operated with a minimum of human intervention, controland maintenance. More particularly, a need exists for an automateddevice, system and method that is capable of, without human labor,frying various food products in desired quantities, such as Frenchfries, seasoning the cooked food and packaging the cooked food inindividual portion-sized containers.

DETAILED DESCRIPTION OF THE INVENTION General

In accordance with the present invention, an automated food processingsystem and method is provided. The automated food processing system andmethod in accordance with the invention allows food to be dispensed,fried and packaged in a suitable container or alternatively dispensed toa food holding area for subsequent processing by a human operator.

Referring to the Figures generally and in particular to FIGS. 1 and 3,there is illustrated an automated food processing system 100 inaccordance with the invention. Automated food processing system 100includes a food dispensing device 200, a fry device 400 and a foodpackaging device 600. In accordance with one embodiment of the presentinvention, each of dispensing, fry and packaging devices 200, 400 and600, respectively, can be constructed and are sometimes illustrated in“modular” construction or form. By “modular” construction or form it ismeant that dispensing, fry and packaging devices 200, 400 and 600,respectively, can exist and be contained in separate cabinets, forexample, and also operate independently of the other devices. Thus, ifone of dispensing, fry and packaging devices 200, 400 and 600,respectively, are inoperative or are otherwise deactivated, the functionof the deactivated or inoperative device can be performed manually. Forexample, food to be fried could be manually dispensed in place ofdispensing device 200. Alternatively, food to be fried could be fried ina conventional fry vat after being dispensed from dispensing device 200in place of using fry device 400 and food that is dispensed and fried indispensing and fry devices 200 and 400, respectively, could, in turn, bepackaged manually, for example.

To facilitate such modular construction and use, each of dispensing, fryand packaging devices 200, 400 and 600, respectively, can be containedin a separate wheeled cabinet, 202, 402 and 602, respectively, asillustrated in FIG. 1. Alternatively, dispensing, fry and packagingdevices 200, 400 and 600, respectively, could be mounted as a singleunit or in a single cabinet or in “non-modular form,” as desired, ormore than one of such devices 200, 400 and 600 could be so mounted orcombined.

A suitable control system for the dispensing, fry and packaging devicesis also provided. As will be described more completely hereafter, in oneembodiment, the control system includes a central control system 110that can interface with a point-of-sale system 112. The central controlsystem will communicate with separate subcontrol systems 114, 116 and118, one for each of the dispensing, fry and packaging devices 200, 400and 600, respectively. Alternatively, a single central control system(not shown) could be utilized in place of individual control systems foreach of devices 200, 400 and 600. Similarly, as another alternative, asingle central control system could be utilized to control the overalloperation of automated food processing system 100 as well as controllingthe individual functions and aspects of dispensing, fry and packagingdevices 200, 400 and 600.

The basic operations of dispensing device 200, fry device 400 and foodpackaging device 600 will now be briefly discussed and discussed indetail hereafter.

Briefly, dispensing device 200 functions to dispense a quantity of foodto be fried to fry device 400. In one aspect of the invention, anysuitable food dispensing device can be utilized. Dispensing device 200can include a cabinet 202 to house the components of dispensing device200. In one embodiment, cabinet 202 will be refrigerated, preferablybelow 32° F. so that the food contents therein will remain frozen. Thisallows the food stored in dispensing device 200 to remain therein for along period of time, much longer than if the contents were merelyrefrigerated (above freezing) or merely at room temperature.

In the illustrated embodiment, dispensing device 200 includes anuncooked bulk food dispensing container 204. Uncooked bulk fooddispensing container 204 may be utilized for food such as French friesor chicken nuggets, for example. Other types of food may also becontained in a dispenser such as uncooked bulk food dispensing container204. Typically, those types of food would be in the form of relativelysmall pieces compared to relatively large food pieces such as chickenpatties, for example.

For relatively large food pieces, a large food dispensing container isutilized. In one embodiment, the large food dispensing container is inthe form of a magazine food dispenser 206.

Food dispensed from a dispenser of dispensing device 200 is deposited ona conveyor 208 that, in turn, directs the deposited food to a secondaryor dump container 210 for subsequent discharge from dispensing device200.

In the illustrated embodiment, uncooked bulk food dispensing container204, magazine food dispenser 206, conveyor 208 and secondary container210 are contained in cabinet 202, which is a refrigerated environment,preferably maintained below freezing (32° F. or lower).

While any suitable conveyor can be utilized in one aspect, conveyor 208is preferably a vibratory conveyor, vibrated by a suitable vibratorymechanism that vibrates a conveyor body 214. Conveyor body 214 may takethe form of a suitably shaped tray, for example.

By containing the foregoing components in a refrigerated and preferablyfrozen environment, consistency in food preparation and dispensing isachieved, thereby contributing to the overall efficient, effective anduniform performance of automated food processing system 100.

Secondary container 210 can be of a form as desired and includessuitable weighing mechanism 216 to permit a determination of thequantity of food contained in secondary container 210. Weighingmechanism 216 can be any suitable device to weigh the contents orotherwise determine the amount of food in secondary container 210.Weighing mechanism 216 may comprise a load cell or a mechanism fordetermining the volume of food deposited into secondary container 210,for example. In this manner, the amount of food that is charged to frydevice 400 at a particular time can be determined. In addition, weighingmechanism 216 can be operated during operation of conveyor 208 and theoperation of conveyor 208 continued until a desired amount of food isdeposited in secondary container 210. In this manner, a precise amountof food can be delivered to secondary container 210 thereby permittingconsistency and uniformity in the portion of food that is delivered tofry device 400. This is also important to ensure that a sufficientquantity of food is being cooked by automated food processing system100.

Prior to activation of dumping mechanism 218, discharge door 220 ofcabinet 202 is opened by operation of a door opening device which can beany suitable device as desired and in the illustrated embodiment is acylinder 222 attached to discharge door 220 and moveable up and down inthe direction of arrow B. Cabinet 202 is preferably insulated with asuitable insulating material 224 that is also provided in discharge door220. The provision of a suitable insulating material is important,particularly since dispensing device 200 will typically be locatedproximate or adjacent fry device 400 that operates at a substantiallyelevated temperature, thereby typically generating substantial heat.

In the illustrated embodiment, dispensing device 200 includes fourdispensing lanes from which food is discharged from dispensing device200 and to a suitable location such as fry device 400. After dispensingthrough discharge door 220, cylinder 222 is activated to close dischargedoor 220. Similarly, dumping mechanism 218 of secondary container 210 isactivated to return secondary container 210 to its upright position toreceive more food.

Fry device 400 includes a fry wheel 404, a fry vat 406 for containingand heating a suitable cooking oil and a drive mechanism 408 forsuitably rotating fry wheel 404. It is to be understood that inaccordance with one aspect of the invention any suitable frying devicecan be utilized.

In the illustrated embodiment of FIGS. 3 and 11-16, fry device 400includes a plurality, in this case four, of separate fry wheels 404,410, 412 and 414, as well as four separate fry vats 416, 406, 420 and418 and a separate drive mechanism 408 for each fry wheel, eachdedicated to a particular one of fry wheels 404, 410, 412 and 414.

In one embodiment, a separate drive mechanism is provided for each offry wheels 404, 410, 412 and 414 and can be suitably located in cabinet402, preferably in a location that is above the level of cooking oilpresent in the associated one of fry vats 416, 406, 420 and 418,respectively.

The suitable rotation of each of fry wheels 404, 410, 412 and 414 can beas desired to direct food articles loaded therein down and through thefry vat until reaching the other side of the fry vat whereupon the foodarticles are discharged. The rotation can be either continuous or aperiodic incremental rotation. For example, a suitable drive mechanismcan be provided to periodically rotate fry wheel 410 in a desiredrotational increment, which may be based on the number of compartmentscontained in fry wheel 410. In the illustrated embodiment of FIG. 13,for example, fry wheel 410 comprises eight food compartments 422, 424,426, 428, 430, 432, 434, and 436. Each of food compartments 422-436 is aperimeter food compartment and open to the perimeter or exterior of frywheel 410. Each of fry wheels 404, 412 and 414 can be similarlyconfigured.

As described in more detail hereafter, each of compartments 422-436 isformed from a perforated curved compartment forming member 510.

In the rotation of fry wheel 410, a periodic incremental rotation can bebased upon 360° divided by the number of compartments. Thus, forexample, in the illustrated embodiment of FIG. 13, each periodicrotation would consist of a rotation of 360° divided by eightcompartments or a periodic rotation increment of 45°. Thus, asillustrated in FIG. 13, the food contained, in this case French fries,in compartments 424-430 would remain in cooking oil 454 contained in fryvat 406 for all or part of four incremental rotations, after which thefood would be discharged from fry wheel 410 in the next incrementalrotation thereof. For example, as illustrated in FIG. 13, compartment422 is ready to receive a charge of food to be fried, compartment 424has a charge of food that has been just immersed in cooking oil 454.Cooking oil 454 is at a level H as illustrated in FIG. 13, which isdependent upon the amount of food contained in compartments 422-436 thatare submerged in cooking oil 454.

Similarly, compartment 426 has food contained therein that has gonethrough two incremental 45° rotations of fry wheel 410, compartment 428has food contained therein that has undergone three incrementalrotations and food compartment 430 has food contained therein that hasundergone four incremental rotations of fry wheel 410 and compartment432, which is now empty, has discharged the food contained therein uponthe last incremental rotation of fry wheel 410. Thus, upon the nextincremental rotation of fry wheel 410, which is in the clockwisedirection as shown by arrow B of FIG. 13, the food contained in foodcompartment 430, which in this case is a quantity of French fries 455,will be discharged from compartment 430 to the food packaging devicewhich is hereafter briefly described.

Upon discharge of food, which in this case is a quantity of French friesfrom one of compartments 422-436 of a fry wheel, such as fry wheel 410as illustrated in FIG. 3, the food is deposited onto an inlet chute 604of food packaging device 600.

From inlet chute 604, the food from inlet chute 604 received from frywheel 410 is deposited into rotatable food dispensing member 606.Typically, rotatable food dispensing member 606 will be compartmentedinto a plurality of compartments that are arrayed along the periphery ofrotatable food dispensing member 606.

Rotatable food dispensing member 606 has a discharge location todischarge the food deposited therein. The discharge location isgenerally located towards an upper portion of rotatable food dispensingmember 606. A food dispensing chute mechanism 608 is positioned toreceive cooked food from the discharge location of rotatable fooddispensing member 606. In a preferred embodiment, food dispensing chutemechanism 608 incorporates a device for weighing or otherwisedetermining the quantity of food that has been deposited into fooddispensing chute mechanism 608. This ensures that when food is dispensedfrom food dispensing chute mechanism 608 a minimum quantity of food willbe dispensed, thereby ensuring that a container 611 or other packagethat is to receive the food from mechanism 608 will receive a desiredcharge.

Food packaging device 600 preferably also includes a suitable automatedcontainer handling system 610. Automated container handling system 610is capable of, in a preferred embodiment, selecting container 611 of adesired size, retrieving and grasping container 611, erecting unerectedcontainer 611 into an erected form and holding the erected container 611in position to receive food dispensed from food dispensing chutemechanism 608.

After food container 611 receives food from food dispensing chutemechanism 608, automated container handling system 610 is capable ofmoving container 611 having food deposited therein to a containerreceiving receptacle 612 which receptacle 612 can be transported via aconveyor system 614 to a desired location for subsequent pickup ofcontainer 611 having food contained therein by a human operator, forexample.

Preferably, a food overflow collection member is provided to collect anyfood dispensed by food dispensing chute mechanism 608 that is notdeposited into container 611. In one embodiment, the overflow foodcollection device is a rotatable food collection member 613. Overflowfood collection member 613 functions to collect food dispensed by fooddispensing chute mechanism 608 that is not received in container 611 andto recycle food collected by overflow food collection member 613 intofood dispensing chute mechanism 608 for subsequent dispensing to acontainer in a first-in, first-out manner so that overflow food ispromptly recycled to dispensing chute 608 for dispensing to a container.

Preferably, food packaging device 600 is configured to include aprovision by which food contained in packaging device 600 is routed towaste where it is not desired to dispense such food into a foodcontainer. Such a condition could arise, for example, if food is heldfor too long a period in food packaging device 600. This function may beaccomplished, for example, by providing a waste discharge location whichcan be in the form of a waste chute 615 to which food from rotatablefood dispensing member 606 and overflow food collection member 613 canbe directed. In one embodiment, chute mechanism 608 is lowered andmember 606 is rotated to dispense food to chute mechanism 608, which inturn dispenses into member 613. Member 613 is rotated counterclockwiseto deliver food to waste chute 615. This process can be continued untilall of the food in device 600 is so emptied, if desired.

Preferably, a suitable structure for applying a desired quantity ofseasoning to food contained in food packaging device 600 is provided. Inthe embodiment illustrated in FIG. 3, a food seasoning device 616 isprovided. Food seasoning device 616 can be any suitable seasoning deviceas desired. In one embodiment, food seasoning device 616 dispenses adesired quantity of seasoning from a bulk storage container through adelivery tube and onto food located in rotatable food dispensing member606.

Preferably, and in the embodiment illustrated in FIG. 3, a foodseasoning device 616 is provided that directs a desired quantity ofseasoning onto food that is contained in a bottom portion of rotatablefood dispensing member 606 and inlet chute 604 via a seasoningdispensing head 618.

Preferably, conveyor system 614 is composed of a raceway 620 that is anendless loop around the periphery of the top surface of cabinet 602 offood packaging device 600, which in one embodiment can be a modular,wheeled cabinet. Conveyor system 614 causes container receivingreceptacle 612 to travel around raceway 620 to a food container pickuplocation 622 where a human operator can pickup food containers havingfood therein. Preferably, conveyor system 614 includes structure forstopping movement of a container/receiving receptacle 612 at apredetermined location when carrying a food container, such as at foodcontainer pickup location 622. Such structure in one embodiment maycomprise a gate structure 928 or 928′ of FIG. 45 and FIGS. 25-27,respectively, that extends across at least a portion of raceway 620 inthe vicinity of the predetermined location. Any suitable type of barrierstructure can be utilized to prevent the desired movement. Mostpreferably, gate structure 928 or 928′ will be located at a height thatis above the top of the receptacle when located on conveyor system 614so that movement of container/receiving receptacle 612 is prevented orstopped only for a receptacle 612 that has a food container 611 disposedthereon. Note that the pickup location can be configured as desired andslightly different configurations 622 and 622′ are shown in FIG. 45 andFIGS. 25-27, respectively.

Referring to FIG. 2, there is illustrated an alternate embodiment of anautomated food processing system 101 in accordance with the invention.Automated food processing system 101 includes a food dispensing device201 which is similar to food dispensing device 200, previously brieflydescribed, where like reference numerals represent like elements. Fooddispensing device 201 includes fewer uncooked bulk food dispensingcontainers 204 and additional magazine food dispensers that are similarto magazine food dispenser 206, previously referred to. Otherwise,dispensing device 201 is similar to dispensing device 200 previouslydescribed.

Automated food processing system 101 also includes fry device 400, whichhas been described.

One primary distinction between automated food processing system 100 andautomated food processing system 101 is that automated food processingsystem 101 does not include an automated packaging device such asautomated packaging device 600. In place of food packaging device 600, afood storage device 635 is provided. Food storage device 635 allows foodcooked by food frying device 400 to be stored in a heated environmentfor subsequent manual processing. As configured in FIG. 2, food storagedevice 635 includes separate heated product receiving receptacles 637,639, 641 and 643. Each receptacle 637, 639, 641 and 643 is dedicated toreceiving food from a respective one of fry wheels 410, 412, 414 and404, respectively. In addition, each receptacle 637-643 can have placedtherein a suitable container to receive food, such as handled trays 645,647, 649 and 651.

As illustrated in FIG. 2, a food item F is being discharged from frywheel 414 down a chute 653 and into handled tray 649 contained withinheated receptacle 641. Food item F can be stored therein for a period oftime until it is ready for subsequent processing.

Food Dispensing Device

Figures generally and in particular to FIGS. 1-10, there is illustratedvarious embodiments of food dispensing devices and portions thereof inaccordance with the invention.

In one embodiment, food dispensing device 200 is illustrated orpartially illustrated in FIGS. 1 and 3-8. Food dispensing device 200includes a cabinet 202, bulk uncooked food dispensing containers 204,205 and 207, magazine food dispenser 206, 209, 211 and 213, and asuitable conveyor system for each lane 234, 236, 238 and 240 of fooddispensing device 200. Any suitable number of magazine dispensers can beused for a particular lane, such as one, two, three, four, five or more,and the illustrated embodiment of four is merely an example. Asconfigured in FIG. 1, for example, lane 234 receives material from bulkhopper 204, lane 236 receives food material from bulk hopper 205, lane238 receives food material from bulk hopper 207 and lane 240 receivesdispensed food from magazine food dispensers 206, 209, 211 and 213 aswill be described hereinafter in greater detail, particularly withrespect to food dispensing device 201 of FIG. 2, for example.

Each lane 234, 236, 238 and 240 dispenses food that is subsequentlydirected to fry wheels 410, 412, 414 and 404, respectively.

The components of lane 238 will now be described in detail and it is tobe understood that the components of lanes 234 and 236 are similar. Lane238 includes uncooked bulk food dispensing container 207 and a foodhandling system 242 which in this embodiment is identical for each lane234, 236, 238 and 240 as well as for each lane of food dispensing device201. It should be noted that food handling system 242, as for example,illustrated in FIGS. 3-6 is depicted with respect to lane 240 and thatfood handling system 242 is the same for each lane 234, 236, 238 and240.

Food handling system 242 includes conveyor system 208, secondarycontainer 210, weighing mechanism 216 and dumping mechanism 218.Conveyor system 208 includes vibratory mechanism 212 and conveyor body214.

Uncooked bulk food dispensing container 204 can be of a shape anddimension generally as desired. Preferably, uncooked bulk fooddispensing container 204 has an upper opening to permit a supply of foodto be placed in uncooked bulk food dispensing container 204. Upperopening 244 as illustrated is located in an upper rear portion ofuncooked bulk food dispensing container 204 and can be convenientlyaccessed via a rear door 246 of cabinet 202. Rear door 246 preferably isinsulated with suitable insulation material 224.

Uncooked bulk food dispensing container 204 is composed of a pair ofopposed upper sidewalls 248, a pair of generally opposed lower sidewalls250 and front and rear walls 252 and 254, respectively, which connecttogether upper sidewalls 248 and 250 to provide uncooked bulk fooddispensing container 204. Front sidewall 252 includes a lower portion252′ that extends inwardly from top to bottom to further facilitatedischarge of food contained in uncooked bulk food dispensing container204. Preferably, lower generally opposed sidewalls 250 are slightlyindented from top to bottom to facilitate the discharge of food that maybe contained therein.

Uncooked bulk food dispensing container 204 includes a bottom opening256 that permits the discharge of food contained therein. Bottom opening256 can be configured as desired and in the illustrated embodiment theentire bottom of uncooked bulk food dispensing container 204 is open. Inthe illustrated embodiment, uncooked bulk food dispensing container 204is particularly suited for use with food such as French fries andchicken nuggets as well as other types of food of relatively small size.

Uncooked bulk food dispensing container 204 is suitably mounted withincabinet 202. While a suitable mounting structure can be utilized, it ispreferred to utilize a structure that will minimize heat transfer fromthe exterior and through cabinet 202 to uncooked bulk food dispensingcontainer 204, particularly where cabinet 202 is refrigerated,especially where temperatures below freezing are utilized. In thatregard, front mounting bracket 258 and rear mounting bracket 260 eachare configured to minimize heat transfer from cabinet 202 to uncookedbulk food dispensing container 204. In that regard, front mountingbracket 258 and rear mounting bracket 260 include openings, 258′ and260′, respectively, to minimize such heat transfer and to maximizeairflow around the containers 204, 205, 207 and dispensers 206, 209, 211and 213. Similarly, materials of low thermal conductivity can also beutilized, if desired, for brackets 258 and 260. Generally, to minimizeheat transfer and to maximize airflow, the surface area contact andcross-sectional area of mounting brackets 258 and 260 should beminimized to reduce heat transfer and “hot spots” on uncooked bulk fooddispensing container 204.

As illustrated in FIGS. 3 and 4, for example, food contained in uncookedbulk food dispensing container 204 passes through bottom opening 256 andonto conveyor body 214 which in the illustrated embodiment is a suitablydimensioned pan. Conveyor body 214 is suitably mounted to vibratorymechanism 212 to effect vibration of conveyor body 214 as well as foodcontained therein and food contained in uncooked bulk food dispensingcontainer 204, and in particular the lower portion of container 204.This vibration facilitates the discharge of food from uncooked bulk fooddispensing container 204 and causes food contained in conveyor body 214to travel in the direction of arrow G. Any suitable conveyor system canbe used in accordance with one aspect of the invention.

A preferred type of vibratory mechanism is available from FMCTechnologies, Inc. of Chicago, Ill. marketed under the model F-010-B andDF-010-B. Vibratory mechanism 212 is preferably an electromagneticvibrating mechanism. Vibratory mechanism 212 in one embodiment producesa vibrating stroke at the surface of conveyor body 214. The strokeresults from the action of an electromagnet that pulls conveyor body 214sharply down and backward and then allows it to spring up and forward.Typical vibratory mechanisms of this type run at about 3,600vibrations/minute at 60 Hz power. The power of the vibrating stroke canbe controlled by a suitable drive module as is known in the art. In oneembodiment, vibratory mechanism 212 can be operated at about 85% of fullpower during filling of secondary container 210 with food. For the firstpart of a fill cycle of secondary container 210, vibratory mechanism 212can be run continuously, then pulsed by turning its power on and offperiodically so that vibratory mechanism 212 operates about 50% of thetime to finish filling secondary container 210 with a desired quantityof food, thereby providing better control on the last part of the foodcharged to secondary container 210.

Food dispensing device 200 preferably includes a suitable mechanism todetermine the weight or volume of a charge of food delivered by conveyorsystem 208 to secondary container 210. The amount may be determinedeither by weight or volume, for example. In the illustrated embodiment,weighing mechanism 216 is operatively interfaced with secondarycontainer 210 to provide an indication of the weight of food containedin secondary container 210. The weight sensed in secondary container 210by weighing mechanism 216 is communicated with control system 114 offood dispensing device 200. Control system 114 monitors and controls theoperative functions of food dispensing device 200 as hereinafterdescribed in greater detail.

Optionally, a level sensor can be employed in uncooked bulk fooddispensing container 204 to provide an indication of the amount of foodstored therein that is available for dispensing. Any suitable levelindicator known in the art can be utilized in accordance with theinvention such as photoelectric, weight, turning fork and others, forexample.

Secondary container 210 can be considered as a dump container and asassociated therewith, dumping mechanism 218 for rotating secondarycontainer 210 through an arc as indicated by arrow B sufficiently todump the contents of secondary container 210. Any suitable dumpingmechanism can be utilized. Illustrated dumping mechanism 218 includes adump cylinder 264 that is secured to a base 266. Dump cylinder 264 canselectively rotate a drive gear or wheel 268 that, in turn, isoperatively associated with a follower gear or wheel 270 to causerotation of follower gear or wheel 270. Secondary container 210 isrigidly secured to follower gear or wheel 270 so that when follower gearor wheel 270 is rotated by drive gear or wheel 268 secondary container210 is rotated through an arc that causes secondary container 210 torotate forward to a dumping position as illustrated in phantom lines inFIG. 3 indicated by reference numeral 210′. Such movement is caused byextension of dump cylinder 264. Similarly, retraction of dump cylinder264 moves secondary container 210 from the dump position indicated byreference numeral 210′ to the upright position indicated by referencenumeral 210 in FIG. 3 where secondary container 210 is ready to receivea charge of food from conveyor system 208, which in the illustratedembodiment the food is French fries FF.

An alternative embodiment for secondary container 210 is illustrated inFIG. 4A. Secondary container 210″ is composed of a pair of opposedspaced apart sidewalls 211′ (only one sidewall 211′ is illustrated andis depicted in a half-moon configuration) and a pair of sidewalls 213 aand 213 b, oriented in a V-shaped relationship when container 210″ isconfigured to receive food from conveyor body 214. Sidewall 213 a ismounted for pivotal movement about apex 215 of sidewalls 213 a and 213b. Such movement is accomplished by a drive mechanism similar tocylinder 264, drive gear 268 and driven gear 270, which in thisembodiment are cylinder 264′, drive gear 268′ and driven gear 270′,which gear 270′ is attached to sidewall 213 a. When cylinder 264′ isextended, sidewall 213 a is caused to pivot downwardly as indicated byarrow AA to the position of sidewall 213 a shown in phantom, therebycausing the contents (French fries FF) of container 210″ to be dumped.Sidewalls 211′ act as sidewall guides for sidewalls 213 a and 213 b whensidewall 213 a is in a lowered position, in which case sidewalls 213 aand 213 b act as a chute or slide.

Control system 114 coordinates the operation of the various functions offood dispensing device 200. For example, when food dispensing device 200is ready to dump a charge of food from secondary container 210 out offood dispensing device 200, control system 262 activates cylinder 222 toopen discharge door 220 thereby permitting the food charge in secondarycontainer 210 to be dumped by dumping mechanism 218 through opendischarge door 220. After dumping of the food charge is completed,control system 114 causes dump cylinder 264 to be retracted therebyreturning secondary container 210 to a position ready to accept afurther charge of food from conveyor system 208. Cylinder 222 has oneend rigidly secured to cabinet 202 or some other suitable location andthe other end of cylinder 222 is attached to discharge door 220.Typically, discharge door 220 will have a suitable guide mechanism,which may be tracks, slots or other suitable apparatus to guidedischarge door 220 to its open and closed positions. Cylinder 222 isoperable to move door 220 up and down as indicated by arrow B in FIG. 6to thereby open and close discharge door 220 as desired. In theillustrated embodiment, discharge door 220 extends across all fourdispensing lanes 226, 228, 230 and 232. If desired, a separate dischargedoor could be provided for each of dispensing lanes 226, 228, 230 and232. In addition, control system 262 causes activation of cylinder 222to close discharge door 220 to prevent heat from entering into cavity272 of food dispensing device 200 in which the food and variousdispensing mechanisms are contained as illustrated in FIGS. 3 and 6, forexample.

Food dispensing device 200 can contain suitable refrigeration components274 such as within a lower portion of cabinet 202 as shown schematicallyin FIG. 1. In accordance with the preferred embodiment of fooddispensing device 200, refrigeration components 274 provide sufficientcooling to provide a below freezing temperature environment in cavity272. Alternatively, suitable refrigeration components can be providedexteriorly of cabinet 202 and even at a remote location as desired. Inaddition, a storage compartment 276 and a storage compartment door 278may also be provided in cabinet 202. An upper side access door may alsobe provided to permit operator access to the interior of cavity 272where uncooked bulk food dispensing containers 204 and/or magazine fooddispensers 206 and/or 209, 211 and 213 are located.

Referring to FIGS. 2 and 7-10, there is illustrated another embodimentof food dispensing device 201 in accordance with the present invention.

Food dispensing device 201 has many similarities to food dispensingdevice 200 previously described where like reference numerals representlike elements. Thus, food dispensing device 201 includes cabinet 202,four product dispensing lanes 226, 228, 230 and 232 with each such laneincorporating conveyor system 208, secondary container 210, vibratorymechanism 212, conveyor body 214, weighing mechanism 216, dumpingmechanism 218, discharge door 220, cylinder 222, insulating material224, food handling system 242, upper opening 244, rear door 246,uncooked bulk food dispensing container 204 which is associated withproduct dispensing lane 234, a dump cylinder 264 for each productdispensing lane, cavity 272, refrigeration components 274, storagecompartment 276 and a storage compartment door 278. Product dispensinglanes 228, 230 and 232 each have associated therewith a plurality ofmagazine food dispensers 280-308 arrayed to provide in the embodimentillustrated in FIG. 9 five magazine food dispensers per productdispensing lane in which there are three product dispensing lanesserviced by the foregoing magazine food dispensers. Consequently,magazine food dispensers are configured in a three-by-five array and aresuspended from a magazine food dispenser support 310 as shown in FIG. 9.Each row of three magazine food dispensers depends from magazine fooddispenser support 310 via a slide assembly 312. Slide assembly 312 issimilar to a drawer slide including a pair of first and second elongatedtelescoping left and right slides 314 and 316, respectively. Suitableupper rollers 318 are mounted to magazine food dispenser support 310 andlower rollers 320 depend from magazine food dispensers 280-308 fortraversing left and right elongated telescoping slides 314 and 316.

Suitable mounting brackets 322 are provided which depend upwardly frommagazine food dispenser support 310 for mounting to cabinet 202.

In addition, suitable mounting brackets 324 are provided which dependdownwardly from magazine food dispenser support 310 for mounting slideassembly 312 thereto allowing magazine food dispensers 280-308 to dependtherefrom.

Magazine food dispenser support 310 has a series of holes 326 and 328therein. Holes 326 can be provided to allow increased airflow andcooling. Holes 328 can also be provided to provide increased airflow andcooling for magazine food dispensers 280-308.

Each of magazine food dispensers 280-308 and 206, 209, 211 and 213briefly discussed with respect to food dispensing device 200 are similarin construction. Magazine food dispenser 206 will be discussed withrespect to FIGS. 7 and 8 and it is to be understood that the othermagazine food dispensers are of similar construction.

Magazine food dispenser 206 includes a body or housing 330 that includessidewalls 332 and 334, front walls 336 and 338 and corresponding rearwalls (not shown) and can be attached in a removable manner if desired,including in a snap-on arrangement to facilitate cleaning. Magazine fooddispenser 206 also includes a top member or cover 340 having mountedthereover a drive mechanism 342. Drive mechanism 342 includes a drivegear or wheel 344 and a driven wheel or gear 346. Depending from each ofdrive wheel or gear 344 and driven wheel or gear 346 is a spiral flightthat is vertically or generally vertically oriented relative to thelongitudinal axis of spiral flights 348 and 350. If desired, a singlespiral flight dispenser (not shown) could also be utilized.

Body 330 of magazine food dispenser 206 can include substantial openportions such as front open portion 352 and a corresponding rear openportion (not shown). Such open portions may have a cover or access doorthereover (not shown). Such open portions can be desirable to permitairflow through magazine food dispenser 206 since generally suchdispenser will be contained in a refrigerated environment and suchopenings help ensure that food contained therein remains frozen orchilled as desired. A vertical divider (not shown) can be providedbetween spiral flights 348 and 350 if desired.

A plurality of generally vertically disposed and spaced apart rods 354,356 and 358 may be provided at the front of magazine food dispenser 206adjacent spiral flights 348 and 350 and similar rods can be provided atthe back of magazine food dispenser 206. Rods 354, 356 and 358 preventfood pieces from falling out of spiral flights 348 and 350 and tomaintain spiral flights 348 and 350 in a vertical orientation.

Magazine food dispenser 206 has an open bottom 360 through which foodpieces can be dispensed during operation.

During operation, drive wheel 344 can be driven by a suitable electricmotor, such as an electric motor 362, 364 and 366 shown with respect tomagazine food dispensers 280, 282 and 284 in FIG. 9. Alternatively,other drive devices could be used, including, for example, a rotary airor hydraulic cylinder. Rotation of drive wheel 344 in a clockwisedirection causes driven wheel 346 to rotate in a counterclockwisedirection by virtue of the intermeshing or contact between drive wheelor gear 344 and driven wheel or gear 346. Such rotation causescorresponding rotation of spiral flights 348 and 350, respectively. Foodcontained by spiral flights 348 and/or 350 is moved downwardly by virtueof such rotation. When such food reaches the bottom of spiral flights348 and/or 350, respectively, such food is discharged from magazine fooddispenser 206 through open bottom 360 and onto conveyor system 208 forhandling as previously described. A single motor could be used to drivea plurality of dispensers 280, 282 and 284, etc. through a suitabledrive mechanism (not shown).

As shown in FIG. 8, pieces of food can be contained by magazine fooddispenser 206 in two different ways. For example, individual pieces offood may each be contained by a single elongated spiral flight 348 or350 as shown with respect to food pieces F1 and F2, respectively. Foodpieces F1 and F2 can be any type of desired food and may be a food itemsuch as a hash brown, an individual portion pie, rectangular food patty,or other type of food as desired. Chicken nuggets and other food canalso be dispensed with the bulk dispenser previously described. Largeritems of food can span across portions of both elongated spiral flights348 and 350 as illustrated with respect to food item F3, which may be alarger food item, such as chicken patty, or other type of food articleas desired. Spiral flights 348 and 350 can be of a desired radialdiameter so that the food piece or pieces that are to be contained anddispensed in magazine food dispenser 206 can be accommodated asillustrated in FIG. 8. Each spiral can contain a food piece so that asillustrated in FIG. 7, the illustrated spirals of spiral flights 348 and350 could each accommodate twelve food pieces such as food pieces F1 orF2 for a total of twenty-four food pieces or twelve food pieces such asfood piece F3 of FIG. 8. As will be appreciated, spiral flights having agreater or lesser number of flights can be used if desired to hold agreater or lesser number of food pieces, respectively.

A suitable home position sensor 362′ can be utilized to indicate a homeor start position of each of spiral flights 348 and 350. As illustratedin FIG. 7, a pair of position indicating sensors 362′ and 364′ areutilized and mounted on drive wheel 344 180° apart for more preciselocating of the position of spiral flights 348 and 350. Sensors 362′ and364′ can be proximity sensors that align with corresponding sensorpickups on the respective drive gear or motor for magazine fooddispenser 206 (not shown).

Preferably, spiral flights 348 and 350 are offset by one rotation sothat a single food item such as food item F1 or F2 in FIG. 8 will bedispensed from one of either spiral flight 348 or 350 for each one-halfrotation of spiral flights 348 and 350.

Preferably, food dispensing device 200 and food dispensing device 201are constructed in modular form, an example of which is illustrated inFIGS. 1 and 2, respectively. Wheels 368 are provided to permit cabinets202, 402 and 602 to be suitably transported across a relatively flatsurface, such as a restaurant work area floor.

Food Frying Device

Referring to the Figures generally, and in particular to FIGS. 1-2 and11-24, there is illustrated fry device 400 and various components andalternative components thereof in accordance with the invention.

In one embodiment, fry device 400 includes cabinet 402, four fry wheels404, 410, 412 and 414, four fry vats 406, 416, 418 and 420, four drivemechanisms 408, one for each of fry wheels 404, 410, 412 and 414. Eachfry vat 406, 416, 418 and 420 is dimensioned to contain a desired volumeof a suitable cooking oil. Each fry vat 406, 416, 418 and 420 isdedicated to one of fry wheels 404, 410, 412 and 414, respectively.

In operation in the preferred embodiment, fry device 400 is positionedto receive the food dispensed from a food dispensing device, such asfood dispensing device 200 and food dispensing device 201. Consequently,it is advantageous to position fry device 400 adjacent food dispensingdevice 200 or 201 as illustrated in FIGS. 1 and 2, respectively. Asuitable control panel 456 can be provided and located in a suitablelocation, such as on the side of cabinet 402. In the illustratedembodiment, control panel 456 contains a separate display for each offry wheels 404, 410, 412 and 414 referred to by reference numerals 456a-d, respectively. Control panels and displays 456 a-d can includeinformation such as set cycle time, oil temperature, oil level as wellas controls to adjust cycle time and oil temperature, for example.

Referring to FIG. 13, there is illustrated fry wheel 410. Fry wheel 410includes two opposed circular spaced apart circular disks 458 a and 458b. Disks 458 a and 458 b can include a plurality of apertures 460 asdesired to reduce wheel weight and to provide circulation of cooking oiland to permit passage of water vapor therethrough, such as during fryingfood products, for example. A fry wheel axle 462 is provided to whichdisks 458 a and 458 b are mounted. Axle 462 is suitably mounted,typically and preferably for rotation with respect to fry vat 406 at alocation above the normal level of cooking oil or range of levels ofcooking oil that will be encountered in fry vat 406 during operation.

In one embodiment, outer peripheral edge 464 of each of disks 458 a and458 b include a plurality of teeth 466.

Teeth 466 can be utilized to drive fry wheel 410 in a manner ashereinafter described. Referring to FIGS. 14-16, there is illustrated insectional view of disk 458 a of fry wheel 410, a portion of which islocated within fry vat 406. A drive wheel 468 is associated in operativeposition relative to teeth 466 located on outer peripheral edge 464 ofdisk 458 a. Drive wheel 468 can be formed from a disk of material of asuitable thickness having a circumferential groove 470 therein.Circumferential groove 470 is typically at least or slightly greaterthan the thickness of disk 458 a in the area where drive wheel 468 anddisk 458 a are juxtaposed as illustrated in FIGS. 14 and 15. A series ofspaced apart pins 472 extend across circumferential groove 470 and areradially arrayed and spaced from the center of drive wheel 468. Drivewheel 468 includes a central aperture 474 through which a drive axle 476can be mounted. In operation, drive wheel 468 is rotated by drive axle476 with drive wheel 468 being positioned a fixed distance from disk 458a so that pins 472 mesh with teeth 466 when rotated as illustrated inFIG. 14 thereby causing rotation of disk 458 a and consequently frywheel 410 in a direction of rotation opposite to the rotation of drivewheel 468, as indicated by arrows K and L of FIG. 14.

It is to be understood that any suitable drive wheel and drivearrangement can be utilized. For example, in place of drive wheel 468with pins 472, a drive arrangement could be utilized in which a drivegear is utilized to mesh with a corresponding gear located around theperiphery of disk 458 a and/or 458 b, for example. Alternatively, afriction drive system could be utilized in which a friction drive wheelwould contact the edge of one or both of circular disks 458 which couldbe of a design having no teeth therealong, such as illustrated inalternative embodiment wheels 479 and 481 described hereafter. Since thewheel will have cooking oil thereon, the coefficient of friction betweenthe drive wheel and fry wheel will be decreased. Care should be taken toassure that when using a friction drive, sufficient pressure ismaintained between the driving wheel and the fry wheel.

Referring to FIG. 16, there is illustrated a drive mechanism for drivingdrive wheel 468. The drive mechanism includes an electric motor 478, agear reduction drive 480, an output shaft 482, a drive pulley wheel 484,a driven pulley wheel 486 and a drive belt 488 extending around drivepulley wheel 484 and driven pulley wheel 486 to drive axle 476 whichthereby drives drive wheel 468 since the end 476 a of axle 476 is fixedin aperture 474 with respect to drive wheel 468. A shear pin 490 can belocated in a shear pin aperture 492 of drive wheel 468 to retain axle476 in a fixed position relative to drive wheel 468. Axle 476 issuitably contained within an axle journal 494 which, in turn, is mountedto frame 496 to permit movement of axle 476 relative to axle journal 494and frame 496. Similarly, motor 478 and gear reduction drive 480 aresuitably mounted to frame 496. If desired, motor 478 may be a steppermotor.

Typically, it is important that the fry wheel is rotated in periodicincrements for a compartment to be aligned with a respective dischargeslide 498 of fry device 400 or other slide, ramp or discharge locationafter a periodic rotation. Typically, the leading edge 500 of acompartment bottom, such as compartment bottom 432′ of compartment 432as shown in FIG. 13 is aligned with the upper edge of fry vat 406 or thetop edge of discharge chute 498 associated therewith to allow thecontents of compartment 432 to be discharged therefrom. As illustratedin FIG. 13, the contents of compartment 432 have already been dischargedfrom fry wheel 410. This is particularly important where incrementalrotation of fry wheel 410 is utilized as opposed to a continuouslymoving fry wheel. Thus, for incremental rotation it is desirable forbottom edge 500 of compartment 432 to be aligned with discharge 498 orthe upper edge 406′ of fry vat 406. In order to accomplish this, astepper motor can be utilized to drive fry wheel 410. Alternatively, orin addition, the position of the baskets can be sensed and theirposition adjusted accordingly to assure that all baskets are in thecorrect position for loading and discharge during operation. Also,utilizing location sensors allows use of a simple DC or AC motor, asopposed to a stepper or servo motor. Any suitable sensor can be utilizedin conjunction with a control system to control operation of the frywheel drive motor. Suitable sensors include proximity, magnetic reed,Hall Effect, photoelectric and capacitive sensors. Such sensors are wellknown in the art and consequently a detailed description of thosesensors is not included herein.

In accordance with another aspect of the invention, it should beunderstood that the height of cooking oil in one of fry vats 406, 416,418 and 420, such as the level of cooking oil indicated by referenceletter H in FIG. 13 in fry vat 406 will increase or decrease dependingupon the amount of food that is submerged underneath the surface ofcooking oil contained in fry vat 406. Thus, as illustrated in FIG. 13,compartments 424, 426, 428 and 430 each have a charge of food, in thiscase French fries 455 contained therein. Each compartment containsapproximately one pound of French fries 455. Consequently, there areabout four pounds of French fries that are beneath the surface level Hof cooking oil contained in fry vat 406. This quantity of submerged foodraises the level H of cooking oil in fry vat 406. This increase in thelevel of cooking oil can cause the food to be submerged and thereforecooked for a longer of period of time in the cooking oil. For example,contrast the level of cooking oil depicted in FIG. 13 with the level ofcooking oil depicted in FIG. 20 in which a charge of French fries 455 iscontained only within compartment 426. This results in a substantiallyreduced level of cooking oil H′ as indicated in FIG. 20. Thus, thecontrol system for fry device 400 can be adjusted to take into accountfor different levels of cooking oil which can be sensed by a suitablesensor as is known by those skilled in the art (not shown). Whererotation of fry wheel 410 is done incrementally after a period of timeelapses, the period between incremental rotations can be increased ordecreased as desired based on the level of cooking oil present in fryvat 406. For example, in the situation illustrated in FIG. 13, theduration between incremental rotation of fry wheel 410 could bedecreased compared to the situation depicted in FIG. 20 where the levelH′ of cooking oil is significantly lower than the level H of cooking oilin FIG. 13. This assumes that the temperature of cooking oil in each ofthe situations depicted in FIGS. 13 and 20 is substantially the same.Similarly, if a constant rotation fry wheel operation is utilized, suchas where fry wheel 410 would rotate constantly, the rotational speedcould be increased to handle the situation depicted in FIG. 13 comparedto the speed of the wheel that would be utilized for the situation inFIG. 20, where the level H′ of cooking oil in FIG. 20 is significantlyless than the level H of cooking oil in FIG. 13.

Referring to FIGS. 13 and 20, frying device 400 can also include a frywheel follower or “fry wheel liner” 502 which is supported by a frywheel follower support 504. Fry wheel follower 502 is a curvedperforated circular segment having a width approximately equal to thewidth of fry wheel 410. Fry wheel follower 502 is supported by a pair offry wheel follower supports 504 that are spaced apart and connected bylateral supports 506. Fry wheel follower 502 prevents food pieces thatare larger than the perforations in fry wheel follower 502 from fallingfrom fry wheel compartments 422-436 during operation. Preferably, theperforations in fry wheel follower 502 are composed of circular holeshaving a diameter of about 0.187 inches that are in staggered rowshaving a center-to-center hole distance of about 0.312 inches. Fry vat406 includes a suitable heating element 505, illustrated in FIGS. 13, 20and 21.

Referring to FIGS. 17-19 there is illustrated a curved compartmentforming member 438 which is composed of two opposed sidewalls 508 a and508 b that are interconnected by a curved J-shaped member 510 that formscompartment bottom 510 a and compartment top 510 b. Preferably, a wiper512 is suitably mounted to compartment member 510.

A plurality of compartment forming members 438 are mounted together infry wheel 410 to provide a plurality of adjacent peripheral foodcompartments 422-436 as illustrated in FIG. 13. As illustrated in FIG.13, the top of one J-shaped member 510 abuts the bottom of adjacentJ-shaped member 510. Thus, advantageously, a fastening member 514, whichcan be a rivet, for example, that secures wiper 512 to compartmentbottom 510 a of one curved J-shaped member 510 will also pass throughthe compartment top 510 b of the adjacent curved J-shaped member 510.Preferably, wiper 512 has a plurality of transversely extending grooves516 a-f that permit drainage of cooking oil therethrough as wiper 512exits the cooking oil in fry vat 406, for example.

Referring to FIG. 17, opposed sidewalls 508 a,b and curved J-shapedmember 510 are perforated to permit the flow of cooking oil therethroughthereby promoting good heat transfer between the cooking oil containedin fry vat 406 and food contained in one of compartments 422-436 whenimmersed in cooking oil. A suitable hole size is about 0.156 inchesspaced center-to-center about 0.250 inches. Wiper 512 also ensures thatclose contact is maintained between the interface of fry wheel follower502 and the top and bottom ends of each food compartment 422-436 whichin each case will be bounded by one of wipers 512. Any suitable materialcan be used for wiper 512 such as rubber or Teflon, for example.

As an alternative construction, compartments 422-436 could beconstructed from curved J-shaped members 510 without opposed sidewalls508 a and 508 b, in which case the compartment sidewalls could be formedfrom opposed circular disks 458 a and 458 b. In addition, it should beappreciated by one skilled in the art that any desired compartment shapecan be utilized in accordance with the invention as long as the food canbe loaded into the compartment, kept within the compartment duringimmersion in the cooking oil and which compartment shape discharges thefood from the fry wheel.

Referring to FIGS. 21 and 22, there are illustrated further aspects offry device 400. FIG. 21 is a sectional view along line 21-21 of FIG. 20.FIG. 21 illustrates the elements previously described and in additionshows the interface of adjacent fry vats 406 and 420 and in enlargedform in FIG. 22. Disposed between fry vats 406 and 420 is a bankingstrip 518 that bridges the gap between fry vats 406 and 420. Bankingstrip 518 can be in a shape as desired and in the illustrated embodimentis a generally inverted V-shaped strip that spans the gap between fryvats 406 and 420. Banking strip 518 prevents any material that isdischarged between fry wheels 410 and 412 from falling between fry vats406 and 420 and causing such material to fall into one of fry vats 406and 420.

Referring to FIGS. 23 and 24, there are illustrated alternateembodiments of a fry wheel for use in accordance with the invention. Itis to be understood that the fry wheel is capable of numerous changesand rearrangements, and the fry wheel, as well as other components andembodiments of the present invention, is not intended to be limited tothe specific embodiments described herein.

Referring to FIGS. 23 and 24, there are illustrated wire form wheels 479and 481. Each of wheels 479 and 481 has a rim 520 and 522, respectively,constructed of tubing, which can be smooth tubing. Such a wheel could bedriven by a friction wheel, if desired. In each of wheels 479 and 481 aplurality of individual tubular spokes 524 extend from each rim to acorresponding hub assembly 526. An axle 528 connects hubs 526 togetherin each of wheels 479 and 481. Wheel 479 includes a slotted member 530that bridges each pair of spokes 524. Each slotted member 530 includes acentrally disposed slot 532 and a pair of tabs 534 on either side ofslot 532. A plurality of fry baskets 536, one for each slotted member530 or pair of spokes 524 is mounted in a snap-lock relationship to eachslotted member 530. Fry baskets 536 have perforated sides and aperforated bottom and top and can be of a similar configuration aspreviously described with respect to fry wheel 410. Each basket 536 canhave a spring tab member 538 that interlocks with slotted member 530 tosecure fry basket 536 to fry wheel 479 resulting in a finished fry wheel481 as shown in FIG. 24. It is to be understood that the embodimentillustrated in FIGS. 23 and 24 is not limited to snap-in baskets andthat other baskets can be used with the wheel arrangement depicted inFIG. 23 with or without slotted members 530. For example, baskets couldbe welded or otherwise affixed to rim 520 and spokes 524. Each of frybaskets 536 includes perforations 540 on the sides, top and bottomthereof, such as previously described with respect to compartmentforming member 438.

Referring to FIG. 24, there is illustrated an alternative drivemechanism 535 to rotate fry wheel 481. Drive mechanism 535 includes amotor 537, a shaft 539 and drive rollers 541 and structure for supplyinga force in the direction of arrow FW. Drive rollers 541 are mounted onshaft 539 which can be rotated by motor 537 to cause rollers 541, eachaligned with one of rims 522, to rotate, thereby rotating fry wheel 481.A force FW is supplied in the direction of arrow FW to ensure thatrollers 541 impart a sufficient tractive force to cause rotation of frywheel 481. Force FW can be supplied by any suitable structure, includinga spring, a weight or an electromagnet, for example. For example, motor537, shaft 539 and rollers 541 could be mounted on a platform (notshown) that is moveable in the direction of arrow FW and a force couldbe applied to urge the platform in the direction of arrow FW to ensureproper traction of rollers 541. Rollers 541 may be constructed of anysuitable material, including rubber, for example. Motor 537 can becontrolled by fry control 116, for example.

Fry wheel 410 can be rotated as desired so that food deposited in one ofcompartments 422-436 travels through and out of the cooking oil 454until that compartment reaches a discharge location. Thus, in theembodiment illustrated in FIGS. 13 and 20, the rotation is in aclockwise direction as indicated by arrow K in FIG. 13 and arrow K inFIG. 20. The rotation of fry wheel 410 can be either continuous orperiodic. In a periodic rotation, the rotation will typically beincremental, that is, the wheel is rotated to some degree and thenstops. Thereafter, after a set period of time, the wheel undergoesanother periodic rotation. This process continues as each fry basket isrotated through and out of the cooking oil vat and to the dischargelocation. Preferably, each periodic rotation consists of a rotation of360° divided by the number of compartments present in the fry wheel orsome fraction of that periodic rotation increment so that the positionof the wheel can be known without the use of sensors. However, the useof a sensor or sensors to be able to monitor wheel position can also beused either as the primary way of controlling wheel position or as abackup. Also, use of a sensor to determine wheel position allows use ofa standard AC or DC motor. Suitable control of wheel 410 can beaccomplished by fry control 116, for example.

In accordance with the present invention, a basket shaking simulationcan be achieved. Basket shaking simulation can be performed by arelatively slight back and forth rotation of the fry wheel, such as frywheel 410. Thus, the drive mechanism is activated to rotate the frywheel clockwise and counterclockwise through a relatively small degreeof angular rotation to simulate shaking of a fry basket during frying.The back and forth rotation can occur relatively rapidly and typicallythe degree of angular rotation will be in the range of from about 2 toabout 20 degrees. In addition, the periodic rotation in one directionmay be of a larger angle of rotation than the rotation in the otherdirection.

Preferably, the degree of rotation during simulated basket shaking willbe monitored, particularly where the rotation in one direction isgreater than the rotation in the other direction so that the position ofeach basket relative to the discharge location can be monitored by thecontrol system to ensure proper discharge of food from foodcompartments.

Referring to FIG. 64, there is illustrated in partially schematic viewfry device 400 along with portions of food dispensing device 200 andfood packaging device 600. As illustrated in FIG. 64 a hood system 546is provided. Hood system 546 includes a hood structure 548, a filter 542and a drip pan 544.

A suitable air blower (not shown) can be provided to cause air flow tomove within hood system 546 generally in the direction of arrows A1, A2and A3. Filter 542 thus filters particulate matter in air flow A1 thatpasses through filter 542. Drip pan 544 catches any matter that dripsfrom filter 542 that is located above drip pan 544.

Third link 856 is, in turn, connected to frame 776 via a universal jointconnection 864 which is at a distance removed from universal jointconnection 860 which connects third link 856 to second link 854. Anoffset member assembly 866 is rigidly secured to frame 776 and includesan angled block 868 and an offset extension 870 to provide the desiredangled and clearance for universal joint 864 and third link 856.

In operation, when moveable rack member 772 is moved relative to mast768, such as when stop 834 contacts a surface, such as in theillustrated embodiment, countertop surface 636 as illustrated in FIG.36, continued downward vertical movement of mast 768 causes rack member772 to move upwardly relative to mast 768. This causes rotation ofpinion 774 which meshes with rack 824 mounted to rack member 772.Rotation of pinion 774 in a counter-clockwise direction in FIG. 30causes rotation of first link 852. Such rotation causes downwardmovement of that portion of first link 852 that is pivotally connectedto second link 854 via pivot connection 858. Such movement, in turn,causes second link 854 to pivot upwardly about pivot connection 858 in aclockwise direction as viewed in FIG. 30 to cause suction cups 842 and844 to move to a vertically oriented position as depicted in FIGS. 34-37from the horizontally oriented position depicted in FIGS. 30-33. Inaddition, such movement of first link 852 causes movement in rotation ofthird link 856 and universal joint connection 860 and 864 to theposition indicated in FIGS. 34-37. When container grasping member 778 isin the position indicated in FIGS. 34-37, an unerected container held bysuction cups 842 and/or 844 will be vertically oriented when suctioncups 842 and/or 844 are attached to the container sidewall, asillustrated in FIG. 40, for example.

In a typical operation, container retrieving and grasping device 762will be operated to position suction cups 842 and 844 below a containerto be selected from container storage magazine 638. Mast 768 will beraised by operation of vertical translation mechanism 790 to a desiredheight so that suction cups 842 and 844 engage a container contained atthe bottom of container storage magazine 638. Vacuum source 846 isactivated and mast 768 can be lowered to remove a container from adesired one of apertures 720, 722, 724 and 726 of container storagemagazine 638. Carriage system 770 can be activated to move containerretrieving and grasping device 762 laterally to a desired location. Suchlateral movement can be controlled by properly positioned sensors 872,874, 876, 878 and 880, for example. For example, sensor 872 can definethe position to retrieve a container from aperture 720, sensor 876 toretrieve a container from aperture 722, sensor 878 to retrieve acontainer from aperture 724 and sensor 880 to retrieve from aperture726. Sensor 874 can be positioned to define the proper location ofcontainer grasping member 778 to erect the container that has beenretrieved from one of apertures 720, 722, 724 or 726 of containerstorage magazine 638, as hereafter described. After erecting thecontainer, the vacuum applied to suction cups 842 and 844 is released byoperation of release valve 848 which permits suction cups 842 and 844 todisengage and release the container that had been grasped. Mast 768 canthen be raised causing stop 834 to be removed from countertop surface636 and by action of weight 826 and operationally spring 832, causingrack member 772 to move downwardly relative to mast 768 thereby rotatingpinion gear 774 clockwise relative to the position shown in FIG. 34,thereby moving linkage assembly 780 to cause movement of containergrasping member 778 from the position illustrated in FIGS. 34-37 to theposition indicated in FIGS. 30-33, where container grasping member 778is in position to retrieve a desired carton from container storagemagazine 638 in a manner previously described, which includes lateraltranslation of container grasping member 778 by carriage system 770.

Motor 890 drives a drive pulley or gear 892 which, in turn,drives a driven pulley or gear 894. In the case where pulleys areutilized, a belt 896 is used to transmit rotation from pulley 892 topulley 894. Motor 890 can be a stepper router or a servo motor asdesired. Alternatively, an AC or DC motor can be utilized provided thata suitable control is provided so that the orientation of mast 884 canbe determined. A carriage system 898 is utilized to provide the desiredvertical movement of mast 884 in up and down directions. Carriage system898 is similar to carriage system 770 previously described and includesa carriage guide 900, a worm gear 902, a carriage follower 904, a drivemechanism 906 which includes a motor 908 (which can be a servo motor oran AC or DC motor) suitably controlled to drive worm gear 902. Carriagefollower 904 includes a threaded aperture or slot 910 which communicateswith worm gear 902 and a threaded aperture or slot 912 in which guide900 is disposed. A carriage follower interface 914 connects carriagefollower 904 to mast 884 and permits shaft 886 to rotate with respect tocarriage follower interface 914. Thus, in operation, rotation of motor908 rotates worm gear 902 thereby translating carriage follower 904 upor down depending on the direction of rotation. A suitable sensor (notshown) can be employed to determine the height of mast 884 for controlby control system 118 for packaging device 600.

Suitable mounting structure 916 is provided to mount container graspingdevice 764 to a desired location, such as within cabinet 602. A slot andkey arrangement between shaft 886 and mast 884 permits mast 884 to bevertically translated either up or down while shaft 886 is rotated.

Mounted on the upper end of mast 884 is a suction device 918 whichincludes a suction cup 920, a source of vacuum (not shown) for suctioncup 920 and a release valve (not shown) for releasing the vacuum tosuction cup 920. Vacuum can be supplied from within mast 884 to suctioncup 920 by a suitable connection as is known in the art.

Container bottom urging device 766 consists of a mast 922 that isvertically translatable up and down by suitable apparatus (not shown).Such apparatus can be similar to vertical translation mechanism 790previously described with respect to container retrieving and graspingdevice 762. Preferably, mast 922 has a blunt end 924.

In operation, container retrieving and grasping device 762 selects anappropriately sized container from container storage magazine 638 asdirected by the control system for food packaging device 600. Afterretrieving the container, which in this case is container 611, containerretrieving and grasping device 762 moves container 611 to a position asindicated in FIG. 40 against suction cup 920 so that opposed sidewallsof container 611 are grasped by suction cups 840 and 842 of containergrasping member 778.

Next, as shown in FIG. 41, container grasping member 778 is movedlaterally away from suction cup 920 while maintaining suction on suctioncups 840, 842 and 920. Container 611 is partially erected as shown inFIG. 41 with bottom 611 b depending downwardly slightly. Containerbottom urging device 766 is then activated as illustrated in FIG. 42 tourge bottom 611 b of container 611 upwardly into the fully erectedposition. Container grasping member 778 is released and retracted fromcontainer 611 and returned to a horizontal up position to select anotherunerected container for erection.

Next, mast 884 is rotated approximately 90° by motor 890 to placecontainer 611 in discharge position 710 of food dispensing chutemechanism 608. Food dispensing chute mechanism 608 is then lowered todischarge French fries FF therefrom and into container 611. Any Frenchfries that are not received into container 611 are collected by overflowfood collection member 613 which is then rotated clockwise in thedirection of arrow X as shown in FIG. 41 to recycle such French fries toupper chute 686 for subsequent delivery to another container. After theFrench fries are dispensed from food dispensing chute mechanism 608,cylinder 700 is retracted placing food dispensing chute mechanism 608 inthe upper position as shown in FIG. 44. Mast 884 can then be rotatedback and forth slightly (e.g., such as 2° to 20°, for example) tosimulate shaking to dislodge any loose French fries or dangling Frenchfries in container 611 and any dislodged French fries will then fallinto overflow food collection member 613 for subsequent recycling. Mast884 can also be raised and lowered slightly and relatively quicklyeither before, during or after the angular rotation to further simulateshaking. Thereafter, mast 884 is rotated approximately 180° untilcontainer 611 is directly over container-receiving receptacle 612 asindicated by T in FIG. 44. Mast 884 is then lowered by operation ofcarriage system 898 until the bottom of container 611 rests incontainer-receiving receptacle 612. Then, the vacuum supplied to suctioncup 920 is released and suction cup 920 releases from container 611.Mast 884 can then be rotated 90° so that it is in position to receiveanother container to be erected.

Container-receiving receptacle 612 is then transported via conveyorsystem 614 which will now be described in detail.

Conveyor system 614 and portions or elements thereof are illustrated invarious figures including FIGS. 1, 25-29 and 45-50.

Conveyor 614 includes, in the illustrated embodiment, raceway 620 whichcan be formed along the surface of countertop 636 or on some othersurface as desired. Raceway 620 is preferably in the form of acontinuous loop raceway and is defined by spaced apart guides 620 a and620 b mounted to countertop 636 to guide receptacles 612. Conveyorsystem 614 includes one or more and typically a plurality ofcontainer-receiving receptacles 612 which are illustrated in detail inFIGS. 46-50. Conveyor system 614 includes a first gate 926 and secondgate 928. First gate 926 is moveable and typically second gate 928 canbe stationary as hereinafter described.

Conveyor system 614 also includes structure for causing movement ofcontainer-receiving receptacle 612. In the illustrated embodiment,container-receiving receptacles 612 are moved via an endless loop 930that can be located beneath countertop 636. Endless loop 930 carries aplurality of magnets 932 as illustrated in FIGS. 45 and 49, for example.Magnets 932 are spaced along endless loop 930. Endless loop 930 maycomprise a chain or other suitable structure that can be driven by adrive system that includes sprockets 934, 936, 938 and 940. One ofsprockets 934, 936, 938 and 940 can be a driven sprocket.

Any suitable endless loop 930 can be utilized such as a belt or a chain.Pulleys could be used in place of sprockets 934-940. The route ofendless loop 930 follows the route of raceway 620.

Container-receiving receptacle 612 typically includes a base 942 and acontainer-receiving well 944 located over base 942. Base 942 includes anenclosed compartment 946 which can be conveniently accessed by a baseplate 948 located along the bottom of base 942 that is fastened to base942 by suitable fasteners 950. Contained within enclosed compartment 946is a magnet 952.

Container-receiving receptacle 612 follows the movement of magnet 932due to magnetic attraction between magnets 932 and 952 thereby causingmovement of container-receiving receptacle 612 along raceway 620.

Enclosed compartment 946 is dimensioned to permit magnet 952 to be freeto rotate therein allowing container-receiving receptacle 612 to bereadily guided by rails 954 and 956 that are raised above countertop636.

Movable gate 926 prevents movement of container-receiving receptacle 612located thereat as illustrated in FIG. 45. This ensures thatcontainer-receiving receptacle 612 is in position to receive a loadedcontainer of French fries, such as container 611 from container graspingdevice 764. After a filled container is placed on container-receivingreceptacle 612 adjacent moveable gate 926, gate 926 is automaticallyremoved by a suitable mechanism (not shown) to permitcontainer-receiving receptacle 612 thereat to be moved by conveyorsystem 614 until French fry container 611 contained therein contactsgate 928 or receptacle 612 contacts another receptacle that is locatedat pick up area 622 as shown in FIG. 45. Once container 611 is movedfrom receptacle 612 b, receptacle 612 b is then free to move alongraceway 620 and passes underneath second gate 928, which can be astationary gate. Alternatively, second gate 928 could be a moveable gateand could be located at a level that directly prevents movement ofreceptacle 612 b. After receptacle 612 b passes underneath second gate928, receptacle 612 a is moved into the position formerly occupied byreceptacle 612 b provided that receptacle 612 a has a French frycontainer thereon which would then cause receptacle 612 a to be stoppedat gate 928. Similarly, when that container is removed from receptacle612 a, receptacle 612 a would then be free to pass underneath gate 928and around that portion of raceway 620 until encountering gate 926 oranother receptacle that is stopped by gate 926.

Referring to FIGS. 51-60, there is illustrated various views of Frenchfry cartons that are useful in accordance with the present invention.The French fry cartons depicted in FIGS. 51-60 are particularly suitablefor use in conjunction with the present invention since the cartonsreadily stand upright without assistance and can be erected by automatedcontainer handling system 610, previously described.

FIG. 51 illustrates a front elevation view of a carton 1012 that isparticularly suitable for containing French fries, for example. Carton1012 is illustrated in FIG. 51 in an erected or opened position andincludes a pair of opposed curved sidewalls 1014 and 1016 and a bottompanel 1018.

Carton 1012 can be stacked in a collapsed configuration and stored in asuitable magazine, such as container storage magazine 638 as previouslydescribed. When in a collapsed position, carton 1012 is particularlysuited to being opened or erected by pulling sidewalls 1014 and 1016apart and urging bottom panel 1018 upwardly, as described with respectto the erection or opening of container 611 by automated containerhandling system 610. Container or carton 611 is of a design that issimilar to carton 1012.

Carton 1012 also includes two supporting legs 1020, 1022 that extenddownwardly from the lower portions of the overlapping edge portions ofsidewall 1014 indicated by reference numerals 1014 a and 1014 b in FIG.59 and FIG. 53.

Carton 1012 is capable of standing on its own because of legs 1020 and1022 that extend below bottom panel 1018 when carton 1012 is open orerected.

Carton 1012 can be constructed from a single blank of paperboard whichis illustrated in FIG. 59. When constructed, sidewall edge portions 1014a and 1014 b form flaps that are glued to the edges of sidewall 1016 asindicated in FIG. 54, for example.

Bottom panel 1018 is specially configured to facilitate opening orerection of carton 1012 by an automated carton handling device such asautomated container handling system 610, previously described in detail.Bottom panel 1018 includes intersecting lines 1024 and 1026.Intersecting lines 1024 and 1026 intersect at a generally centrallocation of bottom panel 1014, which panel is generally oval even thoughit may incorporate straight edges 1028 and 1030, for example.Intersecting lines 1024 and 1026 may be fold lines, lines of weakening,score lines or even perforations. All such structures are referred toherein with respect to intersecting lines 1024 and 1026 of bottom panel1018 only as “fold lines.” Typically, the intersection of fold lines1024 and 1026 form an angle in the range of from about 60° and about120°. In one embodiment, the intersecting bottom panel fold lines areoriented such that one of said lines (fold line 1024 in FIG. 59) isnormal or at least generally normal to curved sidewalls 1014 and 1016.In such embodiment, the other of the intersecting fold lines (in thiscase fold line 1026) is at least generally parallel to curved sidewalls1014 and 1016.

Preferably, fold line 1024 extends from sidewall 1014 to sidewall 1016.

As previously mentioned, carton 1012 is foldable to a collapsed positionwith sidewalls 1014 and 1016 being planar and in contacting overlyingrelation to each other with bottom panel 1018 being divided into twooverlying panels 1018 a and 1018 b by intersecting fold line 1026.

Preferably, bottom panel 1018 includes two additional fold lines 1032and 1034 on either side of fold line 1024 that extends from one cartonsidewall to the other, in this case from sidewall 1014 to sidewall 1016.Secondary fold lines 1032 and 1034 further facilitate the opening orerection of container 1012 with an automated device such as automatedcontainer handling system 610.

FIG. 58 illustrates a carton 1036 that is similar in construction tocarton 1012 previously described except that carton 1036 is of adifferent size.

Preferably, carton 1012 is configured such that the width of the base isrelatively narrow and the sidewalls 1014 and 1016 flare outwardly sothat container 1012 is substantially wider at the top (from about 1.6 to2 or more times the base width). This allows relatively large and tallcontainers to be placed in an automobile cup holder CH as depicted inFIG. 56.

Referring to FIG. 2, there is illustrated an alternate embodiment of anautomated food processing system 101 in accordance with the invention.Automated food processing system 101 includes a food dispensing device201 which is similar to food dispensing 200, previously brieflydescribed, where like reference numerals represent like elements. Fooddispensing device 201 includes fewer uncooked bulk food dispensingcontainers 204 and additional magazine food dispensers that are similarto magazine food dispenser 206, previously referred to. Otherwise,dispensing device 201 is similar to dispensing device 200 previouslydescribed.

Automated food processing system 101 also includes fry device 400 whichhas been described.

One primary distinction between automated food processing system 100 andautomated food processing system 101 is that automated food processingsystem 101 does not include an automated packaging device such asautomated packaging device 600. In place of food packaging device 600, afood storage device 635 is provided. Food storage device 635 allows foodcooked by food frying device 400 to be stored in a heated environmentfor subsequent manual processing. As configured in FIG. 2, food storagedevice 635 includes separate product receiving receptacles 637, 639, 641and 643. Each receptacle 637, 639, 641 and 643 is dedicated to receivingfood from a respective one of fry wheels 410, 412, 414 and 404,respectively. In addition, each receptacle 637-643 can have placedtherein a suitable container to receive food, such as handled trays 645,647, 649 and 651.

As illustrated in FIG. 2, a food item F is being discharged from frywheel 414 down a chute 653 and into handled tray 649 contained withinheated receptacle 641. Food item F can be stored therein for a period oftime until it is ready for subsequent processing.

Referring to FIGS. 62 and 63, there is illustrated heated receptacle 643in a cross-sectional view and FIG. 63 is a cross-sectional view takenalong line 63-63 of FIG. 62 showing the entire width of receptacle 643.

As illustrated in FIGS. 62 and 63, heated receptacle 643 is a heatedwell having a heating element that heats sidewalls 962, 964, 966 and 968as well as bottom 970 of heated receptacle 643. Heating element 960 isin close proximity to walls 962, 964, 966 and 968 as well as bottom 970.Heating element 960 may be composed of a single heating element ormultiple heating elements as desired. Suitable controls may be providedto adjust the temperature of walls 962-968 as well as bottom 970 ofheated receptacle 643. In addition, suitable insulation 972 can becontained within the cavity that is defined by cabinet 974 of foodstorage device 635, which is partially shown in FIGS. 62 and 63.

Preferably, handled trays 645-651, such as handled tray 651 depicted inFIGS. 62 and 63 are dimensioned such that they are in close proximity towalls 962-968 and bottom 970 when placed in heated receptacle 643.

Food packaging device 600 may optionally include food seasoning device616, which is illustrated in detail in FIGS. 65-68. Food seasoningdevice 616 includes a hopper 972, a metering wheel 974, a wheel drivesystem 976, a dispensing tube 978 and a dispersion head 618.

Hopper 972 is configured to hold a desired bulk quantity of a seasoningmaterial, such as salt S. Bulk hopper 972 includes a lid 982 that can beremoved to replenish the supply of salt S contained therein. Hopper 972can have a bottom with inwardly extending sidewalls 984 to facilitatethe dispensing of material from bottom 986 of hopper 972 which mayinclude a dispensing tube 988.

Metering wheel 974 is located beneath bottom 986 and dispensing tube 988to receive a charge of salt or other seasoning therefrom. Metering wheel974 includes a cavity 990 for receiving a charge of salt from dispensingtube 988. Metering wheel 974 is rotatably mounted in a housing 992 andcan be rotated about the longitudinal axis of metering wheel 974 tocause cavity 990 to be directed downwardly which thereby causes theseasoning or salt contained in cavity 990 to fall by gravity therefrom.

Metering wheel 974 is suitably rotated by wheel drive system 976. Wheeldrive system 976 can be controlled by a suitable electronic controlsystem that can form part of the food packaging device 600. Typically,in operation, when French fries FF are dispensed from one or more of frywheels 404, 410, 412 and 414 onto chute 604, a suitable sensing device(not shown) senses the presence of French fries and activates wheeldrive system 976 of automated food seasoning device 616 to discharge apredetermined quantity of seasoning, such as salt, onto the French friesthat traverse chute 604.

Dispensing head 618 can be located in a desired position to applyseasoning to the food traversing chute 604. As illustrated in FIG. 3,for example, dispensing head 618 can be located towards a bottom portionof inlet chute 604 and may extend over a portion of rotatable fooddispensing member 606.

Wheel drive system 976 as illustrated in FIGS. 65-68 includes a solenoidplunger 994 for driving a linkage 996 that is connected to meteringwheel 974 to impart rotation to metering wheel 974. Linkage 996 includesa crank arm 998, one end of which is connected to a central portion ofmetering wheel 974 and the other end is connected to a lever arm 1000which, in turn, is connected to solenoid plunger 994. Lever arm 1000 canbe driven by solenoid plunger 994 which, in turn, causes crank arm 998to be driven, thereby rotating metering wheel 974 sufficiently to causecavity 990 to be directed downwardly, thereby permitting any seasoningor salt contained therein to be dispensed therefrom.

A collection funnel 1002 is disposed at the discharge end of housing 992and connects to dispensing tube 978. Dispensing tube 978 is, in turn,connected to dispensing head 618.

Dispensing head 618 can include a plurality of vanes 1004 forfacilitating dispersion of seasoning dispensed therefrom. Asillustrated, there are four vanes 1004 spaced 90° from each other.

Dispensing tube 978 has a lower end portion 1006 that terminates somedistance above dispensing cone 1008 of dispensing head 618. In oneembodiment, lower end portion 1006 of dispensing tube 978 may terminateapproximately 0.25 inches from the tip of dispersion cone 1008.

Dispersion cone 1008 includes a plurality of holes 1010 that are arrayedthrough dispersion cone 1008 to facilitate the distribution of seasoningor salt. In operation, as salt or seasoning is dispensed through lowerend portion 1006 of dispensing tube 978, the seasoning strikes the topportion of dispersion cone 1008 and is directed into four quadrants viavanes 1004. As the seasoning traverses the surface of dispersion cone1008, some of the seasoning falls through holes 1010 in dispersion cone1008. Note that not all of holes 1010 are labeled, for purposes ofclarity in the Figures. Other salt or seasoning particles do not fallthrough holes 1010 but fall off the lower end of dispersion cone 1008.Still other seasoning particles bounce or are otherwise deflected offthe top surface of dispersion cone 1008 and fall a lateral distanceremoved from dispersion cone 1008. In this manner, a good distributionof seasoning is achieved over a relatively large area.

The Control System and Method

In one embodiment, the System Master Controller of a Server (PC),includes a router/hub, and a touch-screen monitor (user interface). TheMaster can utilize existing technology to integrate, to manage, tocontrol, and to coordinate information flow of and through the varioussubsystems for overall system operation. The network technology is fullycompliant with the latest version of the industry's NAFEM Protocol.

Control System Features

Referring to FIGS. 69-73, the primary functions of the Control Systemare to receive order information from the POS and to connect andcoordinate all operating subsystem controllers with the MasterController so that operational commands and functional information canbe communicated and displayed. The result is that all the dispensing,fry and packaging modules function as one integrated fried foodsproduction system.

In one embodiment, the Control System is event and demand driven. Thatis, nothing happens unless a functional component or subsystem receivesa command signal to initiate the action. In a normal operation mode, thePOS will provide virtually all of the system order demands. These cantake the form of a string of two-bit Order Events. Typically this willbe a quantity and an item (for example, 2 each regular size fries). Theproduct description can consist of both the food item and its portionsize, treated as one bit of information.

The Control System information can be categorized into Order Events,Inbound Events, and Outbound Events. The Order Events come fromprimarily the POS system, the historical kitchen management system (KMS)data, or the touch-screen Monitor if a manager wants to override theautomatic ordering. KMS is a database of information of, for example,the sales rate of various products versus day and time. The Order Eventsdictate and demand the operation and performance of the automationcontrol system for production. The Inbound Events information includesmessages generated by subsystem controllers other than the POS or KMS.The Outbound Events include typical command messages issued by theMaster Controller specifying functions to be performed by individualsubsystem controllers.

In one embodiment, the Master Controller is configured to monitorperiodically or continuously the network for events to occur. Once anevent takes place and a signal is sent on the network, the MasterController identifies the source of the signal, then compares it to theprogrammed schedule of events within its memory, and reactsappropriately, either sending out a new command, showing a display,storing information in memory, or all of the above.

An important source of data for the Control System can be the KitchenManagement System (KMS). The KMS is a historical database of operationalinformation. This information can be used to set the workstationconfiguration, process settings, inventory levels, and set a level ofproduction in advance of actual customer demand orders. This interfacecan be a two-way connection, so that all operational data from the FriedFoods Workstation can be received and stored in the KMS and/or theControl System, or evaluated, adjusted, and re-entered to “fine-tune”the process on a continuing basis.

Generally, the Control System can comprise two loops, shown in FIG. 70.The primary loop is the “Order-to-Package” loop, whereby the MasterControl takes an Order Event input from the POS and directs theappropriate Packaging Module subsystem to package and deliver anappropriate portion of product. A secondary loop is the “BufferReplacement” loop, where the Master Controller receives an Inbound Eventsignal from the Packaging Module that its buffer inventory ofready-to-package fried product is low and additional product must bedispensed and fried. As currently specified, all products other thansalted French fries typically can have a default buffer inventory ofzero, meaning that an order for that (other) product will immediatelyinitiate a full dispense-fry-package (if packaged by the System)production routine.

In accordance with one aspect of this embodiment of the Control System,the Fryer Module vat operation is not directly controlled by theproduction demand cycle. Each fry vat of the fry module will operatecontinuously and on a pre-set uniform operating cycle. Frozen product isdropped into the fry module when additional inventory is called for. Theproduct is fried according to the pre-set cooking cycle and then isdumped into the Packaging (or Protein) Module receiving apron. None ofthe cooking cycle is affected by order demands, or inventory conditions.In one embodiment, the Control System can vary the time betweenincremental rotation and speed of rotation of fry wheel 410 toaccommodate for varying conditions, such as the level of cooking oil inthe fry vat. The level of cooking oil can vary as a result of the amountof product that is being fried in a particular fry vat, since productpresent in the fry vat displaces cooking oil, thereby raising the levelof cooking oil in the fry vat particularly since the product is heldbelow the cooking oil surface during a cooking cycle.

Preferably, to ensure the workstation reliability and system uptime,extensive control redundancy can be provided. As a result, the controlsubsystems for each Fryer Module vat and each Dispensing Module chuteare designed and constructed as individual units that operate even ifone or more subsystem fails.

Additionally, the control of the Dispensing Module freezer environmentand operation can be an independent subsystem.

Preferably, the Control System includes the capability to operate allmodules individually. This allows the operator to disconnect and removea module from the network and operate the remaining modules in asemi-automatic method, manually performing some of the operations.Preferably, there are controls on each module that permit an operator tooperate that module's functions locally.

Orders for product are preferably processed sequentially as they arereceived, although the specific products within a customer order may bearranged in a logical manner as desired. The Monitor will display allproducts being processed by the workstation from the time the order isreceived until it is removed from the workstation. The status of eachproduct that is ordered can be tracked in its various stages including,for example, on order, packaged and ready to pick up, ready to manuallypackage, and held too long.

Preferably, products in the process of being fried can also be tracked,and cooking times for each basket in each wheel will count down to whenproduct is ready to package.

Master Controller

In one embodiment, the Master Controller 110 hardware may suitablycomprise, or equivalent:

-   -   Intel Pentium III (or higher) with 1.0 GHz (or higher) CPU    -   Ethernet network interface and hub    -   256 MB (or more) system RAM    -   20 GB (or more) hard disk drive    -   Touch-Screen Monitor Interface    -   Plug and Play Touch-Screen Monitor    -   SCK Gateway (Ethernet)    -   Interconnect cabling (as needed)    -   Optional Keyboard and pointing device (mouse) for installation        and maintenance purposes

Typical operating system software requirements are:

-   -   Windows 2000 professional (or server) SP4 or higher    -   A suitable Database Server, such as Fast SCK Version 3.0 (or        higher) from Fast, Inc. of Strafford, Conn.    -   Fast SCK Version 3.0 (or higher) Utility Applications (SCK        Editor, SCK Engine, SCK Events, and SCK Site Editor) from Fast,        Inc.        The Subsystem Interface Modules provide the functionality to        communicate specific control events (information) conditions,        and/or commands to and from the Master Controller. These modules        typically can be incorporated into the circuitry of controller        boards. In cases where the network needs to interface with a        control subsystem (such as PLCs, for example), appropriate        imbedded memory interface (input-output) circuit cards known in        the art can be utilized. All of the foregoing hardware and        software or equivalent is readily available or can be produced        by those skilled in the art.        Fryer Controller

The frying of the frozen product is controlled by a combination ofcooking oil temperature and the time the frozen product is immersed inthe cooking oil. Frying is accomplished by moving the frozen productthrough the heated cooking oil by a rotating fry wheel. As previouslydescribed, a programmable stepper or other motor can provide the desiredprecisely controlled movement of the fry wheel.

The following Table I lists typical control parameters and severaloptional parameters that can be used, if desired.

FIG. 71 depicts a typical motor/fry wheel/basket cycle. Virtually everyparameter can be fixed or adjustable as desired. For example, during onetypical cycle, which may be for a preset period of time that isone-quarter of the cooking time for food contained in a compartment, frywheel 410 is rotated clockwise 45° in the direction of arrow K of FIG.13. After some period of time after the 45° incremental rotation, abasket shaking simulation of back and forth rotation occurs over aperiod of about two seconds. After a 0 to 10 second delay, anotherbasket simulation shaking occurs. Thereafter, a period of time (“BasketLoad Window’) is available for loading another compartment, such ascompartment 436 with a charge of French fries or other food to be fried.Thereafter, a “no load zone” or relatively short period of time towardsthe end of the cycle is set aside just prior to another 45° fry wheel410 rotation in the direction of arrow K, which commences another cycle.During each cycle, three “home routines” can be employed, one after eachrotation of fry wheel 410 to accurately locate fry wheel 410 so that itis properly positioned with the upper end of compartment bottom 432′ ofone of fry wheel 410 compartments adjacent discharge 498 and another ofthe compartments properly aligned to receive a charge of French fries orother food to be fried, such as from food dispensing device 200.

To ensure proper operation of the basket/fry wheel, includingpositioning the unit precisely for smooth loading and completeunloading, the basket/fry wheel position must be constantlysynchronized. To do this, a “homing” sensor circuit can be utilized thatresets the home position after every move of the wheel. This sensorpreferably is electromagnetic and is impervious to dirt and grease buildup and has no moving parts although any suitable sensor can be used.

Dispensing Controller

The Dispensing Module control system 114 separates functions by theproduct delivery lane they support. In one embodiment, where there arefour delivery lanes, there are four control subsystems. Each subsystemcontrols a vibrating product conveyor, a portioning load cell, and adump actuator. Additionally, there are optional module configurationsthat affect the controls design. If lanes 1, 2, and/or 3 are configuredwith bulk food hoppers, a product level sensor can be provided to alertoperators to reload frozen product before the hopper is empty. If eachof lanes 2, 3 and/or 4 are configured with an array of coil magazinesfor food items, the controls must sequentially switch power to each ofthe motors in the lane to maintain a constant flow of frozen product.

Table II lists defined control signal parameters for each of theDispensing Module Lane controllers:

TABLE II Dispensing Control Signals (One set for each of 4 ProductLanes) Description Input Output Load - Small Qty. X Load - Large Qty. XLoad Coil A X Load Coil B X Load Coil C X Load Coil D X Load Coil E XReady to Dump X Vibrator Frequency X Bulk Fill Level X Time Out XOverweight X Clean Out XFreezer Controller

In addition to properly dispensing products into the Fryer Module, thedispensing device 200 control 114 must also maintain a proper frozenenvironment for all products. To accomplish this, another controllersubsystem can be provided. Table III lists the applicable control signalparameters for the freezer subsystem. A safety circuit interrupts alldispensing activity when the aisle door is opened.

TABLE III Freezer Control Signals Description Input Output Op. Adj. SetTemperature X X Actual Temperature X Aisle Door Open X

The separation of the Dispensing Module controls into these fivesubsystems when there are five makes for a convenient mechanicalarrangement in the base of the module, and allows for the requiredflexibility given the configuration options.

In one embodiment, for manual operation, four “dispense” buttons areprovided, one for each lane. One button would cause the release of apre-set portion of the frozen product for that lane. The controlspreferably should be located so the operator could by visual observationdetermine the appropriate Fryer basket to make sure the productdispenses into the proper basket.

Packaging Controller

Packaging Controller 118 for the Packaging Module incorporates severalevent signal generators for the control system to sense or read. Themain Packaging Module or device 600 elements are depicted in FIGS.25-29. In one embodiment, the Packaging Module or device control systemincludes two subsystems within the Packaging Module, the packagingsubsystem and the heated food storage device 635 that can be used inplace of packaging device 600.

The Packaging Subsystem

The packaging control subsystem initially interfaces with the PackagingModule PLC and sends packaging device 600 a signal to start thesequential operation of packaging one of an appropriately-sized portionof French fries. The actions and reactions of all the electromechanicaldevices (e.g., container handling system 610, dispensing member 606,overflow member 613, load cell 702 and chute mechanism 608) can be, ifdesired, sequenced and controlled by the local on-board controller(i.e., PLC) and not Master Controller 110.

Once the automated arm 764 sets the filled package of fries on conveyor614 and the receptacle load gate 926 opens to allow receptacle 612 tomove to the pick up area, a signal will be sent back to MasterController 110 indicating that the particular order of fries is readyfor pick up. Until that receptacle 612 moves to the return gate 928(located at the operator right front of the Packaging Module) and thegate permits receptacle 612 to move therepast after receptacle 612 isempty, Master Controller 110 will believe (and display) that the orderof fries is waiting to be picked up. Preferably, the crew member willpick up fries from right to left to ensure that the order sequence isfollowed and that the oldest fries are served first.

Because the number of receptacles 612 that can fit between gate 926 andreturn gate 928 typically is limited, Master Controller 110 intelligencepreferably keeps track of how many orders of fries are in the pick upcue. This allows audible/visual alerts to be triggered on the Monitor toremind the crew that orders have been waiting. Also, even if orders arepicked out of sequence, the Master Controller will remember what was onan empty receptacle 612 and clear it when it passes return gate 928.

Preferably, the Master Controller is configured to remember the holdtime of each packaged fry order. If the order has not been picked up intime, the Monitor will alert the operator by audible/visual signal to“waste” that order.

The Secondary Loop

The remainder of the Packaging Module or device 600 control 118functions address the secondary loop, “buffer inventory replacement.”Preferably, there are two typical system requirements for the bufferinventory: (1) there must be a minimum amount of fries in member 606 orchute mechanism 608 to completely fill the next packaging order (thatis, one portion of a given size); and (2) the buffer inventory is lowand needs to be replenished.

For the first requirement, if there is insufficient buffer inventory tofill the package, chute mechanism 608 is disabled and an error messagealarm is sent. This condition should not happen, but the controlintelligence prevents packaging device 600 from under filling an order.

During normal operations, the level of fries in the buffer inventorywill drop to a level where an inventory replenishment order will beinitiated. In that event, Master Controller 110 can signal dispensingdevice 200 to start its fill sequence. This process should typicallystart soon enough that the replacement product can be fried, salted, andadded to the dispensing member 606 before the “out-of-product” conditionis reached. The KMS data can be integrated into the Master Controlintelligence to help insure that there is replacement product in processbefore the actual need arises. This capability minimizes order deliverydelays while also preventing the dispensing member 606 inventory growingbeyond actual need.

The dispensing member 606 inventory can be managed in a number of ways,as desired. For example, any of the following can be utilized andimplemented by one of ordinary skill in the art: (a) direct sensors; (b)a load cell that constantly weighs the buffer inventory; and (c) adynamic empirical calculation.

The dynamic empirical calculation embodiment uses the Master Controllerto constantly calculate how much product has been added to dispensingmember 606, and subtract out the portion packaged, any bonus amount,waste, and a safety factor. This empirical total will then be comparedto pre-set “reload” levels. The formula may also include how muchproduct is in process. In all cases, the buffer inventory level can beadjusted during the day to reflect actual sales levels.

The controls system design for all other (i.e., non-salted French fries)products is that the same control process would be used, but that the“buffer inventory” for those products would be defaulted to zero. Thatis, an order for hash browns would immediately signal an“out-of-inventory” condition and launch an “inventory replacement”command to the dispensing device 200. Later, if the need arises,controller intelligence would allow the operator to utilize some bufferinventory for these products.

Optionally, a provision can be made for unsalted French fries. UnsaltedFrench fries would be handled like the non-French fries products. Whenan order for unsalted French fries is received, Master Controller 110will signal the Packaging Module to move diverter bar 605. The next loadof French fries coming from the Fryer Module will then be diverted to aportion of chute 604 of packaging device 600 for manual packaging. Theextra unsalted fries can be manually returned to chute 604.

An important feature of the automated system is to maintain productintegrity. One facet of that is to dispose of product that has exceededits authorized holding time. Master Controller 110 will remember wheneach load of French fries came out of fry device 400. The mechanicaldesign of packaging device 600 assures a substantially “first in-firstout” product movement. How long the “oldest” fries have been indispensing member 606 is tracked by Master Controller 110 or packagingdevice controller 118, as desired. Whenever the allowable holding timehas been reached, Master Controller 110 will signal the Packaging Modulesubsystem Controller 118 to start the buffer waste cycle (or thepackaging device Controller 118 can directly control this function). Itis possible that some French fries in the buffer will not have reachedtheir limit, but through control parameter refinement, this can beminimized. Table IV lists the control signals for one embodiment of thepackaging control subsystem:

TABLE IV Packaging Control Signals Description Input Output Op. Adj.Package #1 X Package #2 X Package #3 X Package #4 X Divert Fries XProduce #5 X Produce #6 X Produce #7 X Produce #8 X Produce #9 X DumpBuffer X Buffer Low X Buffer Full X Receptacle Loaded X Receptacle EmptyX Time out - System 610 X Product #5 - 9 Picked XHolding Controller

The other control subsystem is that dedicated to holding product atproper temperatures. Generally, a standard temperature controller withtimer channels to manage all holding functions can be utilized, as isknown in the art.

Table V lists the various control parameters for the holding controlsubsystem for food holding device 635:

TABLE V Holding Control Signals Description Input Output Op. Adj. BufferTemp Set X X Buffer Temp Act X Pick Up Temp Set X X Pick Up Temp Act XApron Temp Set X X Apron Temp Act X Holding Temp Set X X Holding TempAct X Holding Time #1 Start X Holding Time #1 End X Holding Time #2Start X Holding Time #1 End XTouch-Screen Monitor

The Touch-Screen Monitor is the primary system user interface and can beconsidered part of the Master Controller configuration. The Monitor hasfour main functions: (1) display the status of fried foods orders; (2)allow the operator to manually control the system; (3) alert theoperator to any needed manual intervention; and (4) allow the operatorto reconfigure the workstation and/or change the individual operatingparameters.

The Monitor display can be configured as desired. Preferably, the maindisplay menu is simple, uncluttered and only presents the basicinformation needed to track ongoing order status. A sample Monitordisplay layout is shown in FIG. 72.

In the illustrated embodiment, products on order would appear ashorizontal rows of the appropriate product (type and portion size) icon,reading from the left edge of the screen. All products from a single POScustomer order would appear on a single line. As additional POS ordersare entered, the screen would refresh, moving the older orders down aline. Products on order, and not yet ready for pick up would appear asgold icons.

Across the bottom of the screen would appear the same number oflocations as there are packaging device 600 receptacles 612 in the pickup zone. As packages of fries are placed on receptacles 612 and thereceptacles 612 travel within the pick up zone, the appropriate iconwill disappear from the “on order” line and reappear as a green icon inthe spot where its receptacle is. When a package is removed from areceptacle and that receptacle passes return gate 928, the display iconwill disappear from the screen.

In one embodiment, should the “hold timer” for a packaged product expirebefore it is picked up, its green icon will change color (i.e., to red)and/or flash. In another embodiment, an audible alarm can be provided aswell, indicating clearly that this product should be wasted.

Across the top of the screen is a line of control “buttons.” There canbe one for each product (again, type and portion size). The system isprogrammed so that touching the button on the screen will enter an orderfor one each of that product. There is also a screen button at the upperright corner of the screen that enables the operator to change thescreen display to the “Settings” screen.

The “Settings” screen layout is depicted in FIG. 73. From this screen,the operator may now configure all the operating settings for theproduct to be run in each product lane. The individual settings mayinclude dispensing load size(s), fry vat temperature, cooking cycletime, buffer inventory level, packaging device Module heater setting,and other settings as desired. In this embodiment, all settings for aparticular product are linked to that product. The operator can merelyscroll in each product lane and signify the product that will be run init. Master Controller 110 will then set all operating parameters forthat product. If it is necessary to check or adjust an individualcontrol setting (such as cook time), the operator can scroll through theitems in the “settings” box for that lane and product. Then, using the“up” and “down” keys, the operator can readjust the setting and pressthe “enter” key to reset.

If required, a secure “manager only screen” can be configured to allowsomeone to adjust and/or reset selected operating parameters. Access tothis screen and these settings would require some type of password toprevent any non-authorized store employee from changing basic systemparameters.

Operator alert messages or alarms (e.g., bulk product low—refill now:“bridging/time out”—clear lane 2; etc.) will appear as an “error messagebox” in the center of the screen, along with some type of audible alarm.
